On an autumn day in 1895, eighteen-year-old Loyd Montgomery shot his parents and a neighbor in a gruesome act that reverberated beyond the small confines of Montgomery's Oregon farming community. The dispassionate slaying and Montgomery's consequent hanging exposed the fault lines of a rapidly industrializing and urbanizing society and revealed the burdens of pioneer narratives boys of the time inherited.In Pioneering Death, Peter Boag examines the Brownsville parricide as an allegory for the destabilizing transitions within the rural United States at the end of the nineteenth century. While pioneer families celebrated and memorialized founders of western white settler society, their children faced a present and future in frightening decline. Connecting a fascinating true-crime story with the broader forces that produced the murders, Boag uncovers how Loyd's violent acts reflected the brutality of American colonizing efforts, the anxieties of global capitalism, and the buried traumas of childhood in the American West.
